a boat costs $16600 and decreased in value by 14% per year. How much will the boat be worth after 11 years?
mr_godi [17]

The worth of boat after 11 years is $ 3159.3013

<em><u>Solution:</u></em>

Given that,

Boat costs $16600 and decreased in value by 14% per year

To find: Worth of boat after 11 years

<em><u>The formula for decreasing function is given as:</u></em>

y = a(1-r)^t

Where,

y is the value after "t" years

t is the number of years

a is the initial value

r is decreasing rate in decimal

<em><u>From given,</u></em>

a = 16600

t = 11

r = 14 \% = \frac{14}{100} = 0.14

<em><u>Substituting the values we get,</u></em>

y = 16600(1-0.14)^{11}\\\\y = 16600(0.86)^{11}\\\\y = 16600 \times 0.1903\\\\y = 3159.3013

Thus the worth of boat after 11 years is $ 3159.3013

If the measure of xyz is 73 what is the measure of xy <br> a.146<br> b.73<br> c.36.5<br> d.107
icang [17]
146. They are asking for the angle XY, the blue line.

For instance, imagine it is 90 deg, instead of 73, it would cut the circle in two, and XY would be 180 deg. Imagine it would be 45 degrees, it would leave a quadrant, and that's 90 deg.

So the angle * 2 (they are different angles)

I think 'TheBestBrain' thought they were asking for the supplementary angle, but I think it is the arc length angle (blue line)
